Pus-forming bacterial cells that form grapelike bunches or clusters and are present in abscesses are called:

• A. Spirilla
• B. Diplococci
• C. Streptococci
• D. Staphylococci

Answer: (D)

Bacteria that divide in multiple planes to form grape-like clusters are Staphylococci. This cluster arrangement is a hallmark of Staphylococcus species, which are known to be pus-forming and frequently involved in abscesses, such as skin boils or infected wounds. In contrast, spirilla are spiral-shaped, diplococci occur in pairs, and streptococci form chains; none of these match the grape-like clustering pattern. So, when you see cocci in clusters associated with pus and abscesses, the organism is most consistent with Staphylococcus.
